クラス: Exploit
エクスプロイトとは、悪意のある目的のためにローカルコンピュータまたはリモートコンピュータ上で実行されているソフトウェアの1つまたは複数の脆弱性を利用するデータまたは実行可能コードを含むプログラムです。多くの場合、悪意のあるユーザーは、悪意のあるコードをインストールするために（たとえば、悪意のあるプログラムを使用して侵害されたWebサイトにすべての訪問者を感染させるために）被害者のコンピュータに侵入するための攻撃を利用します。さらに、悪意のあるコンピューティングは、ユーザから何も要求されずに被害者のコンピュータをハックするためにNet-Wormsによって一般に使用されます。 Nukerのプログラムは悪用のなかでも注目に値する。そのようなプログラムは特別に細工された要求をローカルまたはリモートのコンピュータに送信し、システムがクラッシュする原因となります。プラットフォーム: MSOffice
Microsoft Officeは、マイクロソフトが発行する生産性アプリケーションのマルチプラットフォームスイートです。 Officeアプリケーションは、多くの種類のファイルとコンテンツと互換性があります。ファミリー: Exploit.MSOffice.CVE-2017-8759

Tactics and Techniques: Mitre*
TA0001
Initial Access
The adversary is trying to get into your network. Initial Access consists of techniques that use various entry vectors to gain their initial foothold within a network. Techniques used to gain a foothold include targeted spearphishing and exploiting weaknesses on public-facing web servers. Footholds gained through initial access may allow for continued access, like valid accounts and use of external remote services, or may be limited-use due to changing passwords.
T1566.001
Spearphishing Attachment
Adversaries may send spearphishing emails with a malicious attachment in an attempt to gain access to victim systems. Spearphishing attachment is a specific variant of spearphishing. Spearphishing attachment is different from other forms of spearphishing in that it employs the use of malware attached to an email. All forms of spearphishing are electronically delivered social engineering targeted at a specific individual, company, or industry. In this scenario, adversaries attach a file to the spearphishing email and usually rely upon User Execution to gain execution. Spearphishing may also involve social engineering techniques, such as posing as a trusted source.
TA0002
Execution
The adversary is trying to run malicious code. Execution consists of techniques that result in adversary-controlled code running on a local or remote system. Techniques that run malicious code are often paired with techniques from all other tactics to achieve broader goals, like exploring a network or stealing data. For example, an adversary might use a remote access tool to run a PowerShell script that does Remote System Discovery.
T1204.002
Malicious File
An adversary may rely upon a user opening a malicious file in order to gain execution. Users may be subjected to social engineering to get them to open a file that will lead to code execution. This user action will typically be observed as follow-on behavior from Spearphishing Attachment. Adversaries may use several types of files that require a user to execute them, including .doc, .pdf, .xls, .rtf, .scr, .exe, .lnk, .pif, .cpl, .reg, and .iso.
TA0006
Credential Access
The adversary is trying to steal account names and passwords. Credential Access consists of techniques for stealing credentials like account names and passwords. Techniques used to get credentials include keylogging or credential dumping. Using legitimate credentials can give adversaries access to systems, make them harder to detect, and provide the opportunity to create more accounts to help achieve their goals.
T1003.001
LSASS Memory
Adversaries may attempt to access credential material stored in the process memory of the Local Security Authority Subsystem Service (LSASS). After a user logs on, the system generates and stores a variety of credential materials in LSASS process memory. These credential materials can be harvested by an administrative user or SYSTEM and used to conduct Lateral Movement using Use Alternate Authentication Material.
